Numerical Study of CO2 Removal from Inhalational Anesthesia System by Using Gas-Ionic Liquid Membrane

Inhalational anesthesia is supplied through an assisted ventilation system. It mostly composed of xenon or nitrous oxide, halogenated hydrocarbons (HHCs), and oxygen. In order to reduce costs the compounds, remaining anesthetics present in exhalation are recycled reused, minimize amount fresh anesthesia. An alkali hydroxide mixture (called soda lime) employed remove CO2 from exhalation. However toxic compounds may be formed during reaction lime with hydrocarbons. Ionic liquids (ILs) have several advantages such as non-volatility, functionality, high carbon solubility, low energy requirements for regeneration. framework this research, dioxide removal ionic has been numerically studied. COMSOL multi-physics finite element software applied. solves continuity, fluid flow, diffusion equations. A new algorithm developed calculating infrared (IR) radiation absorption CO2. Its coefficient wavelength-dependent properties. The gaseous calculated by using HITRAN spectral database. found that absorbed almost completely 1-ethyl-3-methylimidazolium dicyanamide ([emim][DCA]) liquid after a period 1000 s. shown can neglected interval below 1.565 μm, then at 1.6 it increases same CO. Thus, possible detect applying laser diode which capable transmit IR wavelength μm. This time function membrane liquid.
